Effect of size of lubrication phase on properties of Ni-graphite abradable seal coating
Ni-graphite abradable seal coatings were deposited by conventional atmospheric plasma spraying system (APS) and high efficiency supersonic atmospheric plasma spraying system (SAPS) respectively. The influence of the size of lubrication phase on mechanical properties, corrosion resistance and erosion...

| description | Ni-graphite abradable seal coatings were deposited by conventional atmospheric plasma spraying system (APS) and high efficiency supersonic atmospheric plasma spraying system (SAPS) respectively. The influence of the size of lubrication phase on mechanical properties, corrosion resistance and erosion resistance of the Ni-graphite coatings was investigated. The results indicate that the graphite phase in the SAPS coating has a smaller size than the APS coating. The bonding strength (21.0 ± 1.4) MPa and surface hardness (92 ± 1) HR15Y of SAPS coating are 29.6 <private-char description="%">%</private-char> and 23.5 <private-char description="%">%</private-char> higher than those of APS coating respectively. The relative erosion rates of APS coating at 30° and 90° angle of attack are 7 <private-char description="%">%</private-char> and 13<private-char description="%">%</private-char> higher than those of SAPS coating respectively, indicating that SAPS coating has a better erosion resistance than APS coating. Both APS coating and SAPS coating exhibit an obvious electrochemical corrosion in acetic acid environment at 250 ℃．However, the corrosion resistance of SAPS coating is better than that of APS coating. |
